Abstract


OBJECTIVE
The perioperative management of antithrombotic therapy is often challenging and it requires a fine balance between the risk of hemorrhage and thrombosis. We aimed to evaluate the antithrombotic management for moderate to high risk patients in real world setting.
METHODS
Among the patients who were consulted to the neurologist for the evaluation of perioperative risk from 2010 to 2012, patients undergoing moderate to high risk surgery and taking antithrombotics within 30 days were identified. We analyzed the timing of discontinuation and reinitiation of antithrombotic drugs before or after surgery as well as the status of bridging therapy. In addition, the conformity with the guideline suggested by American College of Chest Physicians was assessed. The rate of thromboembolic event and major hemorrhage were also investigated.
RESULTS
A total of 329 patients were included. The concordance rate of warfarin stop and restart time with guideline was 23.4% and 10.3%, respectively. Continuing aspirin in patients undergoing coronary artery bypass surgery or non-cardiac surgery in patients with high risk for cardiovascular events were 59.2% and 2.6%, respectively. Bridging therapy was adopted in 92.9% and 81.2% in patients who had received anticoagulant before surgery and who were at high and low risk thromboembolism, respectively. In entire cohorts, 30-day incidence of major bleeding and thromboembolic event were 31.9% and 3.0%. Co-morbid renal disease were shown as independent predictor for major bleeding (adjusted OR 2.65. 95% CI 1.33-5.28).
CONCLUSION
The concordance rate with guideline regarding perioperative antithrombotic use was low and bridging therapy was prevalent in patients undergoing moderate to high risk surgery.
